When performing secondary directory redirection in nginx, it keeps reporting 404. I don’t know how to change it. Is there any way to debug nginx redirection?

1. Check the logs to determine what files are actually accessed by the server.

2. ls <file>, confirm whether the file exists and eliminate configuration errors caused by manual errors.

3. Check the documentation to make sure the configuration is correct.
